1 0 at] whom may concern Be it known that i, lit/ii Glimmer, a citizen oil the lil nited {"il'iates residing; in Burns City and hitate o'l lndiana, have invented new and us fill linproveinei'its in Tire lun'ips of which the following is aspeoilication, reference being; had to the accompanying drawinns.

This inventioi'i is in the Way oi a tire pump for inflating pneumatic automobile tires, or for like purposes.

The object is to provide a simple and. etfieient two-cyliiuler pump, having one eylinder shorter thanthe other so as to equalize the strokes of the pistons.

The drawing shows a perspective view of the pi'imp.

"the invention eonsis's in mounting two unequal pump cylinders l. and 2 on a base 3 and connecting; them ii'iteiJhJrly by a tube t. it CUl'lIlGCtlllQ; hose 5 leads to the tire to be inflated. llh e eylii'ider If is longer than the cylinder 2 and the top ends 6 are closed, except for the piston holes l" and air vents it These cylinders are (EqlllP'pQCl with the usual piston rods 9, pistons 10 andnir valves Ill on the pistons adapted to admit air below the pistons on the upstrokeand to close on the down stroke so as to :lorce air out through the hose 5. A handle post 12 is inoiiinted on the base 3 spaced trom the shorter cylinder 2 and in alignment with the two cylinders. A handle 13 pivoted. at 1.4; to the top oi this post and is extended over and pivoted to the upper ends of the piston rods 9 at the points 15. An

additional brace 16 may be extended out from the post 112 and. engage the cylinders by means of rings ll" interposed in the brace.

This two cylinder pump may be operateiii easily by one hand and the cylinders are so proportioned that their pistons, moving at unequal speech will both reach the top and bottom of their respective cylinders simultaneously.

While it have herein described a certain specific method of constructing and assembling the elements of my invention, it is understood same may be varied in minor details, not departing from the spirit of my invention as defined in the appended claim.

What I entable is: y

it two cylinder tire pump, comprising" a base; a handle post extended vertically tron: the base; a relatively short pump cylinder on the base adjacent the handle post; a relative long pump cylinder on the base and aligned with the handle post and short eyliinler; an air tube interiorly connecting claim to be new and patthe cylinders near their bases; valved pistons mounted in the cylinders; piston rods extended :l'rom the pistons slidingly out through the tops ot the cylinders; and a handle 'iivotally connected to the ends of the handle post and piston rods.
